Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. Here are the common sizes of lumber, and their actual sizes.
The size of wood framing members is standard regardless of species and is typically stocked at lumber yards in nominal widths of 2 to 12 inches, increasing in 2 inch increments. Pre-cut lengths of lumber start at 4 feet long and, increasing by 2 foot increments, can be found up to 24 feet long. Nominal thickness may be 1 inch, 2 inch, 4 inch, 6 inch or 8 inch.
